Adding matrices is easier than you might think! Just find the corresponding positions in each matrix and add the elements in them! This tutorial can show you the entire process step-by-step.
Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.
To subtract matrices, you need to make sure that the matrices have the same dimensions. If they do, match up the corresponding positions in each matrix and subtract away! This tutorial takes you through the steps of subtracting matrices.
